In simulation of VLSI Integrated Circuits (ICs) that operate at considerably high frequencies essential is distributed modeling of interconnects. In this paper a study of algorithms is proposed dedicated to simulation of nonlinear ICs together with their interconnects which are modeled by means of lossy, nondispersive, in general also coupled transmission lines. A vector model of the coupled transmission lines is proposed and discussed. This model is efficiently applicable in transient analysis of ICs where cts with such solution techniques as sparse matrix, band matrix, iterative approach and mixed approach. Numerical complexity of these techniques is analyzed and compared and the best approach is selected. Several simulation results are shown.
